drivers/net/slip/ and make the necessary Kconfig and Makefile
changes.

-config SLIP
-	tristate "SLIP (serial line) support"
-	---help---
-	  Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to
-	  connect to your Internet service provider or to connect to some
-	  other local Unix box or if you want to configure your Linux box as a
-	  Slip/CSlip server for other people to dial in. SLIP (Serial Line
-	  Internet Protocol) is a protocol used to send Internet traffic over
-	  serial connections such as telephone lines or null modem cables;
-	  nowadays, the protocol PPP is more commonly used for this same
-	  purpose.
-
-	  Normally, your access provider has to support SLIP in order for you
-	  to be able to use it, but there is now a SLIP emulator called SLiRP
-	  around (available from
-	  <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
-	  allows you to use SLIP over a regular dial up shell connection. If
-	  you plan to use SLiRP, make sure to say Y to CSLIP, below. The
-	  NET-3-HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>, explains how to
-	  configure SLIP. Note that you don't need this option if you just
-	  want to run term (term is a program which gives you almost full
-	  Internet connectivity if you have a regular dial up shell account on
-	  some Internet connected Unix computer. Read
-	  <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP
-	  support will enlarge your kernel by about 4 KB. If unsure, say N.
-
-	  To compile this driver as a module, choose M here. The module
-	  will be called slip.

-config SLIP_COMPRESSED
-	bool "CSLIP compressed headers"
-	depends on SLIP
-	select SLHC
-	---help---
-	  This protocol is faster than SLIP because it uses compression on the
-	  TCP/IP headers (not on the data itself), but it has to be supported
-	  on both ends. Ask your access provider if you are not sure and
-	  answer Y, just in case. You will still be able to use plain SLIP. If
-	  you plan to use SLiRP, the SLIP emulator (available from
-	  <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
-	  allows you to use SLIP over a regular dial up shell connection, you
-	  definitely want to say Y here. The NET-3-HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>, explains how to configure
-	  CSLIP. This won't enlarge your kernel.

-config SLHC
-	tristate
-	help
-	  This option enables Van Jacobsen serial line header compression
-	  routines.

-config SLIP_SMART
-	bool "Keepalive and linefill"
-	depends on SLIP
-	help
-	  Adds additional capabilities to the SLIP driver to support the
-	  RELCOM line fill and keepalive monitoring. Ideal on poor quality
-	  analogue lines.
-
-config SLIP_MODE_SLIP6
-	bool "Six bit SLIP encapsulation"
-	depends on SLIP
-	help
-	  Just occasionally you may need to run IP over hostile serial
-	  networks that don't pass all control characters or are only seven
-	  bit. Saying Y here adds an extra mode you can use with SLIP:
-	  "slip6". In this mode, SLIP will only send normal ASCII symbols over
-	  the serial device. Naturally, this has to be supported at the other
-	  end of the link as well. It's good enough, for example, to run IP
-	  over the async ports of a Camtec JNT Pad. If unsure, say N.
